Before entering the dampers into operation after their assembly and by sequential checks, the following checks must be carried
out. Visual inspection of proper damper integration , inside damper area, damper blade, contact surfaces and silicon sealing.
Check of thermal protective fuse and closing mechanism. Check the closing function of the damper blade. This can be done by
removing of thermal fuse from damper body.
Before entering the dampers with actuating mechanism into operation after their assembly and by sequential checks. Check of
blade displacement into the breakdown position "CLOSED" can be done after cutting off the actuating mechanism supply (e.g. by
pressing the RESET button at the thermoelectrical starting mechanism BAT or cutting off the supply from ELECTRICAL FIRE
SIGNALISATION). Check of blade displacement back into the "OPEN" position can be done after restoration of power supply (e.g.
by releasing the RESET button or restoration of supply from ELECTRICAL FIRE SIGNALISATION).
Without power supply, the damper can be operated manually and fixed in any required position. Release of the locking mechanism
can be achieved manually or automatically by applying the supply voltage. It is recommended to provide periodical checks,
maintenance and service actions on Fire Equipment by Authorized persons. The authorized persons can be trained by Producer,
or by authorized Distributor. All effective safety standards and directives must be observed during fire damper assembly.
